Latin for grad gift inscription? "Plunge into Life!"

Hi! I’m hoping to obtain/confirm the correct Latin translation for an inscription on a watch I’m giving my daughter for graduation. It’s a dive watch (she does scuba), so I want to say, in the imperative sense, “Plunge [yourself] into life!” (with a double connotation, of plunging into water/plunging or boldly immersing into life). I’d rather not use “urinare” for obvious reasons, but a friend suggested “In Vitam Immerge.” Is that correct? Any corrections or better suggestions?
Thanks in advance for your help!

It think it needs the reflexive:

Te in vitam immerge.

Thank you!
